In this plot it is interesting to see that tracks with a high instrumentalness, have a lower arousal and tempo. This will be the foundation for further analysis. On the basis of the features valence, arousal, tempo and instrumentalness one could say that lo-l-1 and reinout-w-2 are eachother extremes. How can we visualize these extremes?
These chromagrams represent the intensity of different pitch classes
over time. This visualization highlights the harmonic content of the
track, showing which notes are most prominent at each moment. Patterns
in the chromagram indicate key changes, chord progressions, or repeating
harmonic structures. While the track of Lo is mostly in pitch class G,
the track of reinout does not cointain a certain pitchclass.
These self-similarity matrix’ are based on chroma features. This matrix
reveals structural characteristics of the track by comparing its
harmonic content over time. A strong diagonal line indicates perfect
self-similarity, meaning the music remains consistent over time.
Additionally, block-like patterns suggest recurring sections, such as
verses and choruses, while grid-like formations may be linked to
rhythmic consistency or percussive elements. The track of Lo gives a
beautiful grid-pattern, in contrary to the track of Reinout. The mix of
bright and dark regions suggests variations in melodic or harmonic
content, meaning the song follows a structured composition with repeated
themes and distinct transitions, which is not the case with the track of
Reinout. The matrix of Reinouts track indicates a lot of changes
continuously without repeating motifs or sections.
These self-similarity matrix’ are based on timbre features. Timbre refers to the texture and tone color of the sound, often influenced by instrument choice and production techniques. This matrix reveals a structured musical piece with clear repetition. The strong diagonal line again indicates self-similarity, while variations in the matrix suggest dynamic changes in instrumentation and sonic texture. Grid-like formations may indicate rhythmically consistent elements, while larger block structures suggest repeated themes or motifs across different sections of the track. The high similarity at the beginning and end of the piece suggests a well-defined structure, potentially featuring repeated introductions and conclusions. Again, here Lo’s track had a obvious grid-structure, which indicates that it is a structured song with well-defined sections. What is interesting to see in Reinouts matrix, is that there is high variation, meaning it does not strongly repeat timbral elements throughout. The bight yellow-green bands on the top and right edges indicate a strong similarity between the beginning and the end of the piece.
These chordogram displays matches with expectations of certain played chords. A template is created to represent the presence or absence of certain traits, such as chords, in a piece of music. This template indicates the amount of energy present in specific chords. The chordogram visualizes the relationship by showing how closely the audio matches the template. In the chordogram, dark blue indicates a good match, while yellow indicates a poor match, making it easier to identify which chords are most prominent in the audio. As you can see in the chordogram the chords used in the track of Lo are as expected a lot, and are mostly in E and G, while the chordogram has some difficulty making distinctions between g major and g minor, and e minor and e-flat major. Now, for Reinouts track, the chordogram has a lot of difficulty distinguishing between all the chords. There is a lot of variation in the yellows and blues, indicating variation in the chords.
